Review of basic concepts

Voltage – characterizes the potential energy

Current – characterizes the rate of charge transfer

Voltage Transfer Characteristics

Circuit would act as a linear amplifier f li it d f th lit d f

When amplitude of the input signal:

for a limited range of the amplitudes of input signals

When amplitude of the input signal:

Amplitude of the signal is changed

* Phase can be changed as well but let’s forget about it for now.


Voltage Transfer Characteristics

More complicated shape of VTC

Here output is not linear function of input

Need DC bias !!!

Bias

Differential voltage gain

10

Now, in biased amplifier the output signal amplitude is linear function of input amplitude as long as input is kept within certain range.


Amplifier equivalent circuit for signals

For time variable signals: DC voltage = zero signal voltage = short circuitDC current = zero signal current = open circuit

Output impedance of biased amplifier

Input impedance of biased amplifier
